AUTOMOBILE `:BUMPER ,AND CLAMP.

Application vled April 26, 1926. Serial No. 104,780.

This invention Arelates to automobile bumpers and to the .clamps used in' connection therewith and has for .an object to improve the endof the impact member' of. the `bumper so that it will' notcatch on obstacles when the vehicle backs up; another object of .the invention -is an improved clamp whereby the impact members of the bumper canbe assembled in straight lengths thereby reducing the cost of labor and material in manufacture. Other objects of the invenly tion will appear from the following specification and the accompanying drawings, in which, Fig. 1, is a plan view of one form of my invention, Fig. 2 is an elevation from the impact side of the bumper shown in Fig.

, 1, Fig. 3 is a plan view. o f a modified form of my invention, B l the parts, Fig. 5 is a sectionalyview of the clamp vfor at bars and Fig. 6 is anelevation of my improved clamp.` In the "manufacture of. the of automobile bumpersia pair ,of para-lei bars are usually placed in front Vto receive the impact anda rearba'r is provided to support the impact members and to receive the attaching brackets. The rear .bar is shorter than the impact bars so'that the latter project beyond the rear bar and if curved rearwardly these ends are liable to hook upon objects as the car movesbackwards. In the present invention a member is linked to the endofthe impact members whichturns inwardly and forms-a-loop at the projecting vends ofthe impact members so that the open Y hook construction isfavoided and the ends of theimpact members are reinforced.

Where arallel impact bars are used theyy are usual y secured together by means of eyes in the ends which are connected by end posts. vSome advantage arises in the manuf facture of these bars if lthe eyes can be eliminated and the bars retain their flat shape throughout. The present invention embodies a clamp for this lpurpose with means for 'taking up lost` motion-arising in the clamp. This clamp is assembled by one bolt. A 4 Referring to the drawings, 11 and 12 are the impactv bars, which, in Fig. 1, are held in verhaal-parallel relation by the end osts 13. The rear bar is indicated by 14 w ich is looped at the ends at 15 and'clampedto the. impact barsat 16. The supportingbrackets 18 are secured' to the rear bar at 17.

The loop member 19, Fig. 4, is secured ig. 4 is a detail of one of y fpopula'r ty 'esy to the end post 13 by the eye 21 and has au inwardpoff-set at 20 where the end aligns with the impact barsand is clamped in place by the clamp 16. It will be observed from Fig. 1 that this forms a closed loop on the end of the impact bars which slopes on both sides towards the point and thus prevents the ends of theimpact bars hooking on objects, at the same time these ends are conslderably reinforced by this lloop construction.

The eneral construction in Fig. 3 is siml ilar to ig. 1 except that the end posts are omitted Aand the clam s A25 are .used instead of the end posts. hese clamps are constructed as shown in Figs. 5 and 6. The clamping plate is. turned over at the ends .to enga e the edges ofthe impact bars 11 and 12 4w ile the'wedge piece 27 with taf pered edges'at 31 bythe action ofl the bolt 26 forces the impact bars apart and under the ledges 33 of the plate 25. Lost motion straight lengths and can be polished on a' series of rollers automaticallyr operated.

= The bumper can be packed insmaller compass and can readily be assembled.

v .Having thusv described my invention, I- claim:v

lll)

1. In an automobile bumper, the combination 4of an impact member, a rear supportin bar spaced from and connected with sai impact member intermediate` its ends anda member forming afloop with the end of said impact member and havingitsv free end bent lwardly to clamp against said 'impact memr. l

2. In an automobile bumper, the combination of anim act member, a rear supporting bar spaced impact member intermediate its ends and a loop member connected with the end of saidV impact member` with its free end bent inwardly and 'clamped between the end of the rear bar and the. impact member.

rom and connected withl said f `bent to form a closed loop with the impact members at theibumper end, the inner end.

of said loop member being clamped to said impact members.v

4. In an automobile Vbumper clamp, the combination of a pair of impact members placed vertically in parallel relation, a clamping plate engaging the outer edges of "'f said impact members with a taper engagement and a wedge and bolt for forcingl said members into engagement with said lclamp-` ing plate.

5.' n an automobile bumper clamp, the combination of a pair of impact members placed vertically in parallel relation, notches 1n the outer edges of said'impact members, a 'clamping plate engaging said notches and a wedge and bolt for forcing said members into engagement with said notches.

6. In an automobile bumper clamp, the combination of a pair of impact members l placed in parallel relation and spaced from each other, ajclamping plate passing across said members and engaging a tapered notch in the outer edges of said members, a wedge between said members and a bolt clamping said plate and wedge in position.

ln testimony whereof l affix my signature.
